Description

Technical Field

[0001] This invention belongs to the field of automated logistics technology, and further to the field of automatic material sorting technology, and particularly relates to an automatic opening device and method for multi-specification boxes. Background Technology

[0002] The success rate and efficiency of the seam-opening device are key indicators reflecting the level of box opening technology. In the field of logistics technology, automatic box opening has become an indispensable technology in automated production systems, and the seam-opening device is a crucial link in the box opening system. Therefore, the seam-opening capability of the seam-opening device directly affects the technical level of the box opening system, and thus affects the technical level of the production system.

[0003] For example, a box-cutting machine and its box-cutting method (publication number CN114348383A) discloses that it can process boxes of different specifications, and the side stamping and center seam cutting functions are set in two workstations. The height measurement power is driven by a motor, but there are many workstations and the area occupied is large.

[0004] For example, a box opening mechanism, box opening device, and box opening method (publication number CN114348382A) discloses that it can handle boxes of different specifications and integrates side punching and center seam cutting functions into one workstation, reducing the equipment's floor space. However, the height measurement power is driven by a motor, which makes the structure relatively complex, occupies a large space, has relatively poor maintainability, and the opening process involves many actions, which to some extent affects the opening efficiency.

[0005] Currently, the slit-opening devices on the market have complex structures and occupy a large area. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by integrating the center seam marking and side stamping functions into one workstation. This results in a smaller equipment footprint and reduced equipment costs. The side stamping action is performed simultaneously, reducing the movement of the mechanism, decreasing the time required to open the box, and improving the opening efficiency.

[0007] The technical solution of the present invention is as follows:

[0008] This invention discloses an automatic seam-opening device for multi-specification boxes, including a seam-opening component and a centering component. The seam-opening component is installed on a linear guide rail of an inner frame and located on both sides of a conveying component. The centering component is installed below the inner frame and connected to the seam-opening component. The seam-opening component includes a height-measuring component, a seam-opening mechanism, a swing arm component, and a lifting component. The height-measuring component and the seam-opening mechanism are both installed on the linear guide rail. The swing arm component is connected to the height-measuring component and the seam-opening mechanism. The lifting component lifts the seam-opening mechanism, which in turn drives the swing arm component to move. The swing arm component then drives the height-measuring component to move.

[0009] The height measurement function of the multi-specification automatic seam opening device described above is achieved by lifting the seam opening mechanism through a lifting component, which in turn drives the swing arm component. The swing arm component then drives the height measurement component, causing the height measurement component and the seam opening mechanism to move up and down along a linear guide rail. The ratio of the distance between the height measurement surface and the conveying surface of the height measurement component to the distance between the cutting surface and the conveying surface of the seam opening component remains constant at 2:1 throughout the operation. This allows the seam opening mechanism to automatically align its blades and accurately locate the seam in the box. Power is provided by a power cylinder, and the swing arm drives the seam opening mechanism to complete a series of actions. The device is reliable, simple in structure, occupies little space, and is easy to install, debug, and maintain.

[0010] Furthermore, the centering component includes a connecting seat, a power cylinder, a bearing, and a synchronous reversing device. The power cylinder provides power, and under the action of the synchronous reversing device, it drives the slotted component to perform synchronous reverse linear motion, thereby achieving the centering and positioning of the box in a synchronous clamping manner.

[0011] In the above structure, the slit opening component 6 is connected to the synchronous backstop device of the centering component 3, so that they are simultaneously centered and opened, automatically adapting to the length L of the box.

[0012] Furthermore, the seam-opening mechanism includes a center seam mounting plate, on which a side-punch I mounting plate, a side-punch II mounting plate, and a center seam-splitting power cylinder are respectively mounted. The side-punch I mounting plate is equipped with a short side-punch I power cylinder and a side-punch I serrated blade connected to the short side-punch I power cylinder via a side-punch I connecting plate. The side-punch II mounting plate is equipped with a long side-punch II power cylinder and a side-punch II serrated blade connected to the long side-punch II power cylinder via a side-punch II connecting plate. The center seam-splitting power cylinder is mounted on the center seam mounting plate, which is equipped with a center seam-splitting guide rail. The swing arm assembly is connected to the center seam-splitting guide rail, and the lifting assembly is connected to the center seam-splitting mounting plate.

[0013] Furthermore, the height measuring component includes a height measuring connecting plate, a height measuring guide rail connected to the left side of the height measuring connecting plate, a height measuring support plate connected to the right side, a high pressure measuring plate provided at the lower end of the other side of the height measuring support plate, a pressure plate positioning detection component installed on the high pressure measuring plate via a mounting plate, and a swing arm assembly connected to the height measuring guide rail.

[0014] Furthermore, the swing arm assembly includes a swing arm, one end of which is fixed by a swing arm mounting seat, and the other end and the middle part are connected to the height measuring guide rail and the center slit guide rail respectively through a swing arm connecting shaft and a swing arm roller; the lifting assembly includes a lifting mounting seat, and a lifting bearing I and a lifting power cylinder mounted on the lifting mounting seat. The lifting power cylinder is equipped with a lifting bearing II and a lifting connecting seat, and the lifting connecting seat is connected to the center slit mounting plate.

[0015] In the above structure, the lifting power cylinder 672 drives the slit-opening mechanism 64 to move up and down, and the swing rod roller 664 moves linearly along the center seam guide rail 655, driving the swing rod assembly 66 to rotate. The other swing rod roller 664 of the swing rod assembly 66 moves linearly along the height measuring guide rail 631, driving the height measuring assembly 63 to move up and down. The height measuring assembly 63 and the slit-opening mechanism 64 move up and down simultaneously along the linear guide rail 62. The ratio of the distance from the height measuring surface of the height measuring assembly 63 to the conveying surface to the distance from the blade surface of the center seam cutter 652 to the conveying surface is always maintained at 2:1 during the operation. The slit-opening mechanism 64 can automatically align the blade and find the center seam of the box, thereby realizing the mechanical height measuring function.

[0016] Furthermore, it also includes a control system, which includes a detection device and a control box. The detection device includes a pneumatic baffle positioning detection component, a housing positioning detection component, an alignment positioning detection component, a height measurement positioning detection component, a center seam marking positioning detection component, and a side-punch positioning detection component. The pneumatic baffle positioning detection component is used to detect whether the pneumatic baffle can block the housing; the housing positioning detection component is used to detect whether the housing is in position; the alignment positioning detection component is used to detect whether the housing is aligned; the height measurement positioning detection component is used to detect whether the seam opening mechanism has completed the blade alignment; the center seam marking positioning detection component is used to detect whether the center seam marking is completed; and the side-punch positioning detection component is used to detect whether the side-punch is completed.

[0017] The control box sends a box feeding command, controls the conveying component to convey the box, and after the smoke detection component is triggered, it issues a smoke blocking command, causing the pneumatic baffle to rise. After the box is in place, the box positioning detection component issues a centering command, and the centering component performs centering. After the centering is completed, the positioning detection component issues a height measurement command, causing the height measurement component to descend and press against the box surface. After the height measurement is completed, the height measurement detection component issues a center seam cutting command. After the center seam cutting is completed, the center seam cutting detection component issues a side punching command. After the side punching is completed, the side punching detection component issues a command to reset the pneumatic baffle, lifting component, and centering component, and the conveying component outputs the box, completing the box opening.

[0018] This invention also discloses an automatic seam-opening method for multi-specification boxes, comprising the following steps:

[0019] Step 1: The pneumatic baffle extends, and the box is stopped when it is conveyed to the pneumatic baffle, thus completing the conveying process.

[0020] Step 2: Centering component operation. After centering is completed, the jacking component lifts the seam opening mechanism, which drives the swing arm component to move. The swing arm component drives the height measuring component to move, so that the height measuring component and the seam opening mechanism move up and down along the linear guide rail. The ratio of the distance from the height measuring surface of the height measuring component to the distance from the cutting surface of the seam opening component to the conveying surface remains a fixed ratio during the operation, thereby realizing automatic cutting of the seam opening mechanism and accurately finding the center seam of the box.

[0021] Step 3: Extend the scriber to cut the center seam and then cut the center seam. Return the scriber to its original position after the center seam is cut.

[0022] Step 4: Extend both the serrated blades of Side Punch I and Side Punch II simultaneously to perform the side punch, and retract them after the side punch is completed;

[0023] Step 5: The pneumatic baffle descends, the lifting assembly resets, the centering component resets, the conveying component outputs the box, and the box opening is completed.

[0024] Furthermore, the specific operation steps in step two are as follows: the lifting power cylinder drives the slit-opening mechanism to perform lifting and lowering movements, the swing rod roller moves linearly along the center seam guide rail, driving the swing rod assembly to perform rotational movements; another swing rod roller of the swing rod assembly moves linearly along the height measuring guide rail, driving the height measuring component to perform lifting and lowering movements; the height measuring component and the slit-opening mechanism simultaneously perform lifting and lowering movements along the linear guide rail, and the ratio of the distance from the height measuring surface of the height measuring component to the conveying surface to the distance from the center seam slit cutter surface to the conveying surface remains a fixed ratio throughout the operation process, and the slit-opening mechanism can automatically align the cutter and accurately locate the center seam of the box, thereby realizing the mechanical height measuring function.

[0025] Further, the specific operation steps in steps three and four are as follows: the center seam telescopic power cylinder moves to extend the center seam cutting blade, the center seam cutting power cylinder moves, the center seam cutting blade cuts the tape on both sides of the box seam simultaneously in one cut, the center seam cutting power cylinder resets, the center seam telescopic power cylinder resets, the center seam positioning detection component is triggered, and the center seam cutting is completed; the side puncture I short power cylinder and the side puncture II long power cylinder move simultaneously, moving the side puncture I serrated blade and the side puncture II serrated blade extend simultaneously to puncture the tape at the four side seams of the box, the side puncture I short power cylinder and the side puncture II long power cylinder resets, the side puncture positioning detection component is triggered, and the side puncture is completed.

[0026] Furthermore, before the box is conveyed, it is laid on its side on the conveying component, so that the orientation of the upper and lower covers of the box is perpendicular to the conveying direction of the conveying component, and the opening directions of the upper and lower covers of the box are upward and downward, respectively.

[0027] Compared with existing technologies, the advantages of this invention are:

[0028] This invention integrates the center seam marking and side stamping functions into one workstation, resulting in a small equipment footprint and significantly reduced equipment costs. The side seam opening of the box body adopts a simultaneous side stamping method, reducing mechanism movements, decreasing seam opening time, and improving opening efficiency. The height measurement function is powered by a power cylinder, driving the seam opening mechanism. A swing arm drives the height measurement component to measure the height, thereby achieving automatic tool setting of the seam opening mechanism. The structure is simple, compact, and has high tool setting accuracy. Attached Figure Description

[0083] Box cutting process:

[0084] Upon receiving a system command, the slit-opening device controls the pneumatic system to execute commands, driving each mechanism of the slit-opening device to move sequentially and continuously. Upon receiving a system feed command, the slit-opening device triggers the pneumatic baffle positioning detection component, causing the pneumatic baffle 7 to extend under the drive of the pneumatic baffle power cylinder. The box body 5 is conveyed by the conveying component 4 to the pneumatic baffle 7 and stopped. After the box body 5 reaches its position, the positioning detection component is triggered, and the conveying component 4 stops conveying. The centering component 3 performs a centering operation under the drive of the centering power cylinder.
